I am new to Linux. I have installed kubuntu using a USB boot on my new PC yesterday, and today I installed gnome as well. I was trying to set up my system and did some research. For some reason, I ran the command
sudo do-release-upgrade and the command line started printing commands. I waited and got a notification saying that I do not have enough disk space. This is what I see on my disk usage analyser.
Also, after the
Low Disk Space on "Filesystem root" notification popped up, my PC freezes and both my mouse and keyboard cannot move. I tried to power off and power on again and nothing is showing after the Kubuntu logo.
Any help is appreciated, thanks in advance.
I went to recovery mode and used that terminal there.
systemctl -p 0..3:
Also, how do I clean up my disk space, will I need to give up my files? and clear my hard disk?
